Abstract: We report on the experimental observation of a new type of dark soliton in afiber laser made of all normal group velocity dispersion fibers. It was shownthat the soliton is formed due to the cross coupling between two differentwavelength laser beams and has the characteristic of separating the twodifferent wavelength laser emissions. Moreover, we show experimentally that thedual-wavelength dark solitons have a much lower pump threshold than that of thenonlinear Schr\-odinger equation dark solitons formed in the same laser.
